At time of writing we are taking a direct hit from the typhoon. It’s the strongest I’ve experienced since I was in Taiwan. The last typhoon I saw in typhoon I saw a roof lifted and dumped onto the road below my apartment, where a driver stopped and stared at it for a good five minutes before his senses returned. Below is the clean up of that roof. I don’t remember why I didn’t photograph the actual incident. I just heard the loud crashing sound from inside my apartment.
Roofs can be deadly flying debris during a typhoon. Photo taken in Taiwan, 2005.
Wind gusts of over 250km/h or about 125kt are strong enough for any flying debris to be deadly. DO NOT GO OUT if it is anywhere close to a super typhoon, and of course do not go out into a super typhoon.
Super typhoons can tear branches of trees and uproot others.
Typhoons can be very dangerous. Here’s a sample of the dangers.
After the rain we were blessed with this amazing sunset. The response to this photograph on Instagram has been amazing. Thank you so much to all those people who enjoyed this photograph and told me by liking it. Your support is really encouraging. #nature #naturephotography #sunset #architecture #weather Update to the JapanesePhotos Instagram at: http://bit.ly/2xCGMqN.
Typhoons are not that dangerous… any more, at least. If you’re super rich and live in a good neighbourhood in a sturdy house, or like most expats, live in a very sturdy apartment or condominium building, there’s nothing to worry about. Basically it’s just a windy, rainy day, and it has no effect on you, whatsoever. However, if you live in a low-lying area, near canals or rivers, in an area with storm-surge barriers near the sea, then you might have something to worry about (think New Orleans). Furthermore, if you live in Taiwan (with dodgy illegal rooftop structures all around you), or other places with flimsy building construction, then you shouldn’t stay too long near the windows or on your balcony and definitely don’t venture out. In countries like China, Philippines, Taiwan, Vietnam, and others there will be a lot of debris flying about.

2. Employers expect you to go to work
That’s right. Even if your home is at risk, and your family too, you’d better have a good reason not to come into work. Fortunately, most companies allow their employees to either stay home or return home when the Japanese Meteorological Agency (JMA) says that their is a “Warning” level for “storms” (or red on the JMA maps, but listed for “storms”). That means that the slow response the JMA has in updating their websites, and the near server crashes they experience from hundreds of thousands of hopeful employees means that when the information finally comes through, many employees could be in the brunt of the typhoon as they are travelling home. In contrast, Taiwan is much, much more organised. When the government announces closures of government offices either the night before or before 7am on the morning of an expected landfall, all businesses follow suit, so no-one is in harms way unnecessarily. I’ve seen news reports in Japan of children at a school sports day being killed by a marque blowing over in the middle of a typhoon. Japanese do tend to deny nature exists. It is a country of engineers and bureaucrats, not humanitarians.
3. Japan Meteorological Agency website is a problem to itself
I guess the JMA doesn’t quite understand that itself is a small natural disaster. Their information does not appear useful to non-Japanese people who are in Japan. On their Japanese version of the website, their typhoon probability circle times are in Tokyo time, but the English side it’s in GMT, a fact I didn’t know for the first eight years I lived in the country (I hadn’t heard of “UTC” until recently). I always wondered why there were such discrepancies in the expected arrival times. Furthermore, the language is not descriptive enough to adequately communicate the level of threat you face. They did bring out a new level last year. So there are now (my translation in parenthesis):
Grey: No warning or advisory (no danger)
Yellow: Advisory (moderate danger)
Red: Warning (high danger; risk of injury and damage)
Purple: Emergency Warning (extremely high danger; expected loss of life and serious damage to property in some places)
Furthermore, they still use Japanese and Japanese-English terms on their English website that no-one else understands. Here are some that you’ll see with a translation (republished from September 2012 JMA Information blog post):
Ku: Ward (like a suburb)
Cho / Mura: Town
Shi: City (like “Nagoya-shi” is just a city called “Nagoya” in regular English)
That’s right, the word “storm” refers to strength of wind, not the normal English definition of violent weather that includes thunder and lighting.
One more thing on this point, JMA doesn’t give names to typhoons, but they count them. The one that is bearing down on me as I write this is “number 18 of 2014”, as you can see here, http://www.jma.go.jp/en/typh/141824.html The English version of the website does include the international name of the typhoon. However, all the local news services refer only to the number, not the name.

4. What is actually dangerous about them in Japan?
Some simple facts. The slower the typhoon moves north, the more energy it has. Also the slower it moves, the more rain will pummel the storm area. The more rain in an area, the greater the risk of run-off overwhelming flood barriers, and the greater the risk of land and mud slides in hilly areas. A slow moving typhoon might track between 8 to 15km/h. A faster moving typhoon might move from about 20 to 25km/h. From about 30km/h it seems they start to loose organisation and fall apart. Also, from eye-balling the JMA satellite imagery, if you can easily and very clearly see a large hole in the centre, the eye, then it’s a seriously strong typhoon (see below). In my experience, the central pressure of typhoons is in the 900-1000hPa range. If it drops quickly, that means it’s getting stronger. I think I have seen typhoons under 900hPa, which is seriously strong and quite dangerous. Wind speeds or gusts over 200km/h is considered strong, but speeds over 300km/h are extremely rare and would make international headlines for weeks to come. The most dangerous or wild part of the typhoon is usually the northern arc, not so much the southern for some strange reason. Rainfall of anything over 150mm (I think in a 24hr period) is expected of almost all typhoons, over 200mm is more normal. However, rainfall in the range of 300 to 400mm is a lot. I think rainfall of 50 to 80mm/hr is a lot and expected in the centre of typhoons.
Typhoon season in Taiwan is typically in July and August. In Japan it is typically in August, but mainly September and October. It’s rare to get one in May, June, or July, but not unheard of. I’ve seen typhoons approach and hit South Korea in August.

5. Blue skies afterwards
Usually after a typhoon all the pollution in the skies have been blown away and you’ll see the most amazing blue skies. Also, it’ll be a hot day, too. I’m not entirely sure why. Typhoons tend to follow the warm or hot ocean currents, but warm air or rather, warm days follow typhoons.
Expect clear blue skies and very warm or hot days after typhoons have past.
NHK can provide updated information about the weather by pressing the d for digital button. It moves the live tv broadcast to the top-right corner, and the digital info layout on the left and across the bottom. Japan now has a three level system which says, from lowest risk to highest: Advisory, Warning, and Emergency Warning. At time of writing, the TV was chiming and putting Japanese language information about evacuations required due to flooding in various districts of Kyoto. Some train services in Nagoya have been closed, and more may be. Despite months ago the Japan Meteorological Agency (JMA) and NHK promising multilingual ticker-tap information, this is not being followed through. Many flights in Nagoya, and presumably Osaka and Tokyo are cancelled.
Typhoons are usually strongest on their north-eastern side, and weaker wind and rain on the south-west. The slower they travel the more dangerous they are, as they spend more time dropping rain in a limited area. The more rain in one area increases the chances of flooding, landslides, and flood barriers and storm surge barriers at rivers and by the sea being washed away causing inundation. Unlike my Taiwan experience, the wind isn’t dangerous, whereas in Taiwan strong winds blow loose roofs off and into the street.
This POTW was originally drafted for Monday the 8th April, but due to technical difficulties it was delayed.
It’s that time of year when the cherry blossoms (sakura) are… were out. They cherry blossoms are usually out in my area now, and would be for the next week or so, at least until the spring breeze blows their fragile petals from their stems. However, due to unseasonally warm weather in the last month, the cherry blossoms bloomed quite early. Also, due to unseasonal weather, most of Japan suffered from high winds, in some areas, classed as strong as typhoon winds, and perhaps more dangerous due to their sustained force. Usually, company groups, community groups, and families go and enjoy picnicing and partying under the gentle pink blossoms in the day or when lit up at night in what’s called ‘hanami’ (cherry blossom viewing) parties. This is also a feature for new recruits to companies who traditionally start in April, as a way of welcoming in the new department employees. This year, I doubt it was much of an event because it was so early, and because of the typhoon like winds on the weekend, which should have been prime cherry blossom viewing party time. Consequently, the best I could do this year is to post a file photo, from 2006 below, and see the gallery for more cherry blossom photos.
Information issued by the Japan Meteorological Agency (JMA) is often unclear and gives a false sense of security. The JMA vocabulary is unique (see image far below). Immediately below are some JMA terms with terms that perhaps better explains what should be intended to be communicated. Much of the vocabulary applies to typhoons, extreme storms, and other natural phenomena. I do not take any responsibility for decisions you make (or fail to make), and the choice of vocabulary is intended to be a guide. It is your responsibility to be well informed both before and during natural disasters and from multiple sources.
JMA vocab:: My interpretation
Warning :: Extreme danger / high possibility of disaster
Advisory :: Moderate danger
Tobu :: Eastern areas
Seibu :: Western areas
JST :: Japan Standard Time
UTC :: Greenwich Mean Time (I don’t know why they don’t use local times)
Storm :: Extremely high danger & extremely strong wind
Gale :: Very strong wind with moderate danger
Other information: Generally, the slower the typhoon the more dangerous it is, as it’s dropping more rain and longer in one area. Also, slow moving typhoons tend to have stronger winds. Slow is about 25km/h or less. Strong winds are about 250km/h. Storm surge is where the typhoon draws air and sea water up, creating an artificial high tide. If a storm surge coincides with high tide, then coastal storm surge defences (sea walls) may have waves washing over them. Some sea walls may have been made with sand in them (back in the 1950’s they didn’t know otherwise), so water may pour through some walls, which will result in the sea walls collapsing. Of course, modern sea walls with concrete and asphalt water proofing is usually safer. Typhoons are typically just big wind storms, so the main danger for 90% of people is having heavy things blown onto their heads. In Taiwan, the biggest cause of deaths is from storm wave watchers getting washed away. It goes without saying, get some extra food, water, batteries, beer, and a warm and cuddly friend, and enjoy a bit of indoor time. 😉 Usually, the eastern side of a typhoon has the worst weather spread over a wider area, but the western side will have weaker weather and over a smaller area.
Many train services will still be running, even in the highest level of weather danger. Transport services will only stop running if there has been damage to train lines. Exception is the bullet train (shinkansen) services, which run by more pragmatic rules. Schools, sports carnivals, and companies will still expect workers to arrive at work before or after a typhoon, except when the company’s policy says otherwise. Most companies and schools say that if the JMA state that there is a Storm level (extremely strong wind) warning issued, then don’t come in or go home; but these are dependent on when the warning was issued. Your company or school with have guidelines clearly spelt out, in Japanese, and so you need the phone number of a buddy who can tell you if you have to work today or not.
There is a heavy rain alert issued by the Japanese Bureau of Meteorology. Already, urban area flooding has occurred, landslides in Gifu and in the south west of Japan. So far, two people are missing in landslide areas in the south. There is a risk of flood barriers collapsing, and threats of inundation. Many residents in low lying areas have been told to be prepared to evacuate at short notice. Some community shelters have already taken in elderly residents, and others who have difficulties moving. My area does have the threat of the local canals (pictured below) over flowing, and fire engines can sometimes be heard with sirens on going around my neighbourhood. Currently, the issued warnings say thunderstorms and dense fog. The full collection of photos in the Disaster gallery.
The complete eclipse, with ring of fire, is due to sweep across Kobe, Osaka, Nagoya, and Tokyo at about Monday, 7.30am, 21st May. However, it depends on the weather, and currently it seems a bit too 50-50 to get excited.
